Apple Inc.

Apple logo.

Apple is a hardware and software company that makes computers, operating systems and mobile devices. They are most famous for the iPhone and iPad products, but also known for their iPod music players, Macintosh computers as well as the Unix-like OS X and iOS operating systems. The Apple brand is more valuable than Coca-Cola.

The company puts a strong focus on the user experience. Their products are extremely well designed with incredible attention paid to detail. Their user interfaces are easy to use, well-designed and look good. However, Apple's platforms tend to be walled gardens; you usually can't do much more than what Apple allows you to do. Apple controls what gets into the App store, which means the software you can install must be approved by Apple. This limitation can be circumvented, but only enthusiasts tend to jailbreak their devices, leaving the average users at the mercy of Apple's will.

OS X

Very capable Unix operating system. Fully POSIX-compliant and with a nice graphical user interface on top. Software availability cannot rival that of Windows's and it tends to be on par with Linux, if not higher.

iPhone

One of the most popular smartphones in the world; it's become an icon and a status symbol. The iPhone boasts high-end hardware and has great build quality. However, it was designed to be operated entirely with one hand and there aren't any options when it comes to screen size. If you like phablets, you are out of luck. It runs the iOS operating system; while its App Store contains a very large collection of high quality applications, it suffers from the walled garden problem the most.

iPad

What happens when you duct tape a bunch of iPhones together.

Macintosh

Apple's line of personal computers. They used to be based on a custom computer architecture, but nowadays they're pretty much exactly like PCs under the hood. They look and feel nice and have great build quality, but will most likely cost way too much money for the hardware you will be getting; the exception being the Mac Pro (a.k.a. the Trash Can), which is cheaper than DIY PCs and, surprisingly, can be upgraded.

Notable products in the line are the iMac, the Mac Pro, the Macbook Pro and the Macbook Air.
